Ubuntu 26.04 Ends 46 Years of Silent sudo Passwords

Ubuntu 26.04 LTS will display asterisks during sudo password entry, ending 46 years of silent password prompts originally designed to prevent shoulder surfing. The change is driven by sudo-rs, a Rust-based rewrite of the classic C sudo implementation that Canonical adopted as default starting with Ubuntu 25.10. The upstream sudo-rs project enabled the pwfeedback option by default, which Canonical cherry-picked into Ubuntu 26.04 builds.
